Researchers at RTU MIREA have developed a modular FDM 3D printer featuring an automated print head exchange system. Based on the Voron open-source project, the device utilizes a magnetic carriage mechanism to switch between two print heads without manual intervention, allowing for the combination of different materials in a single print.
The printer offers a build volume of 300x300x250 mm and reaches print speeds of up to 700 mm/s. It includes a closed chassis, a heated build plate, and an active chamber heating system capable of reaching 80 degrees Celsius. The machine supports various filaments, including PLA, PETG, ABS, TPU, and HIPS.
The development team, consisting of students Nikita Kochetov, Veronika Ermolaeva, and Daniil Kotov, alongside senior lecturer Alexander Lim, created the device as part of the 'Startup as a Diploma' initiative. The project was documented in the proceedings of a national scientific conference.
Future development plans include integrating real-time quality control services to monitor printing processes and reduce material waste. The team has already secured grants for a subsequent project, the INTED MAP modular five-axis 3D printer, building on the experience gained from this prototype.
